Document Summary

Not essential in maintaining homeostasis, but crucial for procreation. The reproductive organ is not a homeostatic organ and we can therefore live without them. The testis, which are located inside the scrotum (the balls) To produce healthy sperm the testis need to be 2 degrees below normal body temperature. They are located outside the body and the cremaster muscles can elevate the position of the testis to regulate temperature. Epididymis: mature, store and transports sperm to the vas deferens. Vas deferens: transports sperm from the epididymis for ejaculation. Seminiferous tubule: location of meiosis and gamete creation (spermatozoa) sperm and sex hormone production (testosterone) Surrounded by leydig cells that produce androgens. Leydig cell: lays outside of the seminiferous tubule (adjacent), produces testosterone in the presence of lh which goes into the blood stream to affect and release androogens. Sertoli cell: testosterone diffuses from the leydig cells to support and regulate spermatogenesis (nourishes developing sperm cells)
